Pipe exposed to direct sunlight... UV Damage Diagnosis
Plastic pipe whitens, yellows or blackens when used outdoors. This is a sign that it is being damaged by UV rays.
If it is continued to be used in that state, it may be damaged by earthquakes or heat shock as a result of sudden impact or oscillation.
The extent to which pipe has deteriorated can be investigated by shutting down the production line, disconnecting the pipe and carrying out a survey of deterioration in its physical properties (destructive testing). However, sometimes production lines cannot be shut down just to carry out a survey.
Use our UV Damage Diagnosis service.
A sample of the discolored pipe surface is scraped off so there is no need to shut down the line.
We analyze the flake samples and estimate the loss of strength and flexibility caused by UV damage.
An efficient way to proceed is to try this service first and then, if considerable damage is suspected, carry out a survey of the deterioration in the pipe’s physical properties.
- Enables diagnosis without stopping the line
- Simply scrapes off flakes from the discolored pipe surface
- Can estimate when pipe will need replacing
